For the first time Packserv's Technical Services has solved a major printing dilemma faced by manufacturers universally.
How to print variable data onto laminated or glossy labels (including thick varnish finishes) where using traditional methods of hot foil coding or thermal transfer printing isn't successful during the automated packaging process.
The solution, Reverse Order Ink Jet Coding.
Adding variable data to 'hard to print/code' labels whilst on the automated production line can be problematic because the label can't be marked once the container has been labelled. Manufacturers who are working with 'hard to print/code' labels such as these need to mark the labels in 'reverse order for ink jet coding', i.e. instead of placing the coder at the end of a production line the coder is placed in between the capping and labelling processes.
Ink jet coders use etching solvent and pigment based ink that etches into any surface or substrate allowing variable data to be successfully added onto any lable before the label ends up on the container. The coder prints onto the label whilse still on the label roll on the automatic labeller (i.e. before the label reaches the container) by taking a signal from the conveyor to know where the container is on the line. At over 500 impressions per minute, an ink jet coder will far outrun hot foil and thermal print methods.
